I love lions even more than the next guy. But if I ever see one in my backyard, I'm going to have a nice trophy for my living room wall.
But I'm good with them sending us mastodons. They're cooler, and less likely to eat my dog.
Are these people crazy? Do they seriously think that animals native to the savannahs of Africa can survive in the climate of the North American plains?
They survive in the climate of North American zoos. They'll be fine, as long as they congregate around swimming pools with air conditioned cabanas.
